Gordon is correct. Install onto each of three computers using the minimal install option, that says the RealTracks etc. will be on the external drive.

Another trick I use is, in Windows, rename the BIAB USB drive to the same high drive letter on each machine (ex. I use drive R for RealTracks), so plugging in other devices doesn't bump up the drive letter. Otherwise, your drive is E sometimes, or F, or ... One reason I do this is to use SyncToy to back up any of my song files, and I never have to create new folder pairs to accommodate changing drive letters.
